Radiation exposure and the effects on human health
A look at what could happen to people who are exposed to radiation in the Japanese nuclear crisis.As engineers have fought to avert a meltdown at the earthquake- and tsunami-crippled Fukushima No. 1 (Daiichi) power plant, nuclear authorities have reported that spikes of radiation have escaped from the facility at levels that can be dangerous to human health. Authorities have evacuated more than 170,000 people within 12 miles of the plant and have warned those within 20 miles to stay indoors and close off ventilation systems. They have also issued iodine tablets to those who have remained in the area and those at evacuation centers. At least 200 people have been exposed to radiation. Here's a look at the potential radiation exposures and effects on human health.
